On Monday, Day released a statement denying that he intentionally stomped on players, alleging it was the result of him hustling through the end of the play.
During both plays, Day was shown running toward a ball carrier and leaping in the air as the ball carrier was tackled. On the first play, he landed on a player's stomach, and on the second, on a player's leg.
According to ESPN, LSU coach Les Miles sent the tapes to the SEC for review.
The SEC said the suspension is "the result of multiple flagrant and unsportsmanlike acts during the game, as well as previous disciplinary action for similar behavior."
Day will miss the game against Texas A&M on Oct. 4.
